Legacy Open Mesh: Link Aggregation On Switches

Follow

Topic

This article describes Link Aggregation and how to implement it on Open Mesh Switches.

Environment

  • Open Mesh Switches

Description

Link Aggregation is the process of combining multiple physical links (ports in case of switches) to form one logical link, for purposes of increasing total available bandwidth, performance and reliability. Link aggregation is most commonly used to link bandwidth intensive devices to the backbone of a network or for connecting core switches with distribution switches, to extend the reach of a network.

Procedure

Navigation

1. Navigate to Manage -> Switches, and select a switch.

2. Click Port Settings.

Grouping Ports

To create a Link Aggregate Group (LAG), follow these steps:

1. Select two or more ports, then click the Aggregate button.

2. A prompt asking "are you sure you wish to aggregate these ports together" will display, as seen in Figure 4. Click OK.

The ports will then merge and display the ports within the LAG, and that they are now in a Group, as seen in Figure 5.

Splitting Ports

To split one or more ports from an existing Link Aggregated Group:

1. Select a LAG, then click the Split button.

3. The Split Grouped Ports window will display, as seen in Figure 8. Select the ports you wish to remove from the group, then click OK.

Removing all ports from a group will remove the group entirely.

Important Notes

  • PoE will automatically disable for all ports within the LAG.
  • The LAG will use the port settings of the lowest number port.
  • Rate limiting is not supported on aggregated ports.
  • Link Aggregation requires devices that support LACP.
